ipmr: Use on-device stats instead of private ones.
These devices use the private area of appropriate size for
statistics. Turning them to use on-device ones make them
"privless" and thus - really small wrt kmalloc cache, they
are allocated from.
Besides, code looks nicer, because of absence of multi-braced
type casts and dereferences.
